Question

Look at the graph:

A coordinate grid from negative 16 to positive 16 is drawn with both in increments of 2. A straight line passing through the points 0, 0, and negative 4, 12 and 4, negative 12 is drawn.

What is the relationship between x and y?

y and x stay constant
y increases as x increases
y decreases as x increases
y stays constant as x increases

Answer 1

any ideas?

Answer 2

not quite

when x = 0, what is y?

Answer 3

good

now, when x = 2, what is y?

Answer 4

nope

Answer 5

read the graph carefully.

Answer 6

nope

Answer 7

x increace y decrease

Answer 8

nope

Answer 9

put your finger on the origin (0,0)

then move your finger to the right 2 units

then move down until you touch the line graph

then move your finger left

which number do you touch?

Answer 10

line is pass through 0,0 so equation of line is y=mx
now watching the line we can that m(slope of line) is negative so if x is increase then y is desearse so option c is correct

Answer 11

ah, sorry for taking so long to get back >>

Answer 12

good, so if y went from 0 to -6, did it increase or decrease?

Answer 13

so, which answer choice do you think it is...?

Answer 14

c
